Abstract

Abstract: In recent years, intensive farming has become the development direction of animal husbandry, with the larger and larger scale of breeding. Especially, as a pillar industry related to people's livelihood, pig breeding accounts for more than half of the whole animal husbandry. On the basis of ensuring the sustainable development of pig breeding industry, how to improve production efficiency and achieve resistance-free farming has become a current research hotspot. As a new type of feed probiotics, Bacillus coagulans has the properties of both lactic acid bacteria and bacillus, which can not only produce lactic acid, but also form spores. There are such functions as improving the intestinal health of pigs, building up the immunity and disease resistance, regulating the balance of intestinal flora and boosting the performance of animal production, so it has a great application prospect in pig breeding. The biological characteristics of Bacillus coagulans were reviewed in this paper. Meanwhile, the paper focuses on the effects of Bacillus coagulans on pig production performance in non-resistant diet, alternative antibiotics, diets containing antibiotics, mixed with other additives and other aspects. Combined with the existing experimental results, the mechanism of Bacillus coagulans on improving the growth performance of pigs was analyzed from the balance of intestinal health, digestion and absorption, immunity and intestinal flora. The problems and suggestions in the application of Bacillus coagulans in pig breeding were also put forward in order to provide reference for the further development and application of Bacillus coagulans preparation.

Key words: Bacillus coagulans; biological characteristics; production and application; action mechanism; pig breeding
